She's really lucky the guy just sat in the cab and fumed instead of paying the guy (so he left) and forcing his way into the house. She could have ended up crying to the cops for entirely different reasons.
As for the decorating.....what else would you put with a velvet Elvis besides a leopard print couch? One woman's tacky is another's unique funky style.
In all fairness, I would be pretty pissed if I were expected to pay half the bills and do half the chores, but not allowed any say in the decor.
